Apple Crumble, King Arthur Recipe

Directions:

1. Preheat oven to 350 degrees F.
2. Peel, core and slice the apples into 1/4-inch-thick pieces.
3. Place them in a bowl with the remainder of the filling ingredients and stir vigorously to combine. In the process, the apple pieces will break into smaller bits; this is fine.
4. Spoon the apple mixture into a lightly greased 9x9 cake pan, or a ceramic pan of similar capacity and surface area.
5. TOPPING:.
6. In a medium bowl, stir together the flour, oats, salt, brown sugar, cinnamon and baking powder. Add the butter, cutting it in as you would when making piecrust.
7. Mix until crumbly; if you work it too much the mixture will clump together, so use a light touch but be thorough.
8. Sprinkle topping over the filling.
9. Bake the crumble for 1-1/2 hours or until it's hot and bubbly and a deep, golden brown. Remove it from the oven and let it cool to lukewarm before serving.
